Breaking the dilemma of agricultural water fee collection in China
Low agricultural water fee collection rates are a problem commonly faced by many developing countries and this is a problem faced by China as it enters the new century. There are two main problem-solving strategies used in different areas of China: increasing the water fee collection rate, or exempting people from paying the water fee. In those areas where the first strategy is pursued, local ...

Modelling Common Agricultural Policy–Water Framework Directive interactions and cost-effectiveness of measures to reduce nitrogen pollution
Selecting cost-effective measures to regulate agricultural water pollution to conform to the Water Framework Directive presents multiple challenges. A bio-economic modelling approach is presented that has been used to explore the water quality and economic effects of the 2003 Common Agricultural Policy Reform and to assess the cost-effectiveness of input quotas and emission standards against ...

Minimal models and agroecological policy at the regional scale: An application to salinity problems in southeastern Australia
A minimal dynamical systems model that couples agricultural activity, native vegetation, and hydrological processes is developed to explore policy options regarding regional-scale soil and water salinization in southeastern Australia. The analysis suggests that although considerable revegetation is required to restore catchment water balance, the current value of water in uses other than ...

Integrated modelling of a coupled water-agricultural system using system dynamics
An integrated System Dynamics Model for the water-stressed Rosetta region, Egypt, assessing water balance, and agricultural yield and revenue to 2050, is presented. The study uses 57 simulations to better understand impacts on water, food and economic security and their interactions, in order to highlight potential pathways towards a more sustainable future for the Rosetta region. Current water ...

Farmers fine-tune research, spread their own innovations
Smallholder farmers can aid the uptake of research fruits and drive grassroots innovations. Joel Winston reports. The 1960s' Green Revolution demonstrated how technological innovations can transform agriculture. High-yielding crop strains, irrigation, fertilisers and pesticides were brought into developing countries, including India and the Philippines, increasing yields by more than 250 per ...
